Shipping to Norway?

If it's possible to get the amp delivered to the airlines that could be another option. I had my Vandersteen's sent to the airport near my home in China. Check with the airlines that fly to the U.S.
I'm not sure if this will be any easier or cheaper but it is worth making a call.

If they're speakers, I wouldn't ship them by air. The pressure change causes a lot of them to lose their ferrofluid. I guess they will leak it somewhere, and may cause damage. Maybe ask the manufacturer first to be sure.

I actually bought my speakers direct from Vandersteen and shipping through the airlines was their suggestion. I've been listening to them for almost four years without an issue.
It is not easy to ship overseas via surface mail now. "try" USPS stopped several years ago. Not sure about UPS? But their cost was way to high for China.

He is shipping an amp anyway:)

Are you sure you want to do it? And is price the object?

Give Panalpina a call or visit their website. The only affiliation I have with them is I move their freight.
